METHOD OF PRODUCING STOCKINGS FOR VARICOSE VEINS Filed June 30, 1949 'AW 0W M/M ATTORNEY Patented June 16, 1953 METHOD OF PRODUCING STOCKINGSFOR VARICOSE VEINS Albert Emile Joseph Marie Neumager,Montceaules-Mines, France, assignor to Varinyl, Montceau-les-Mines,France, a French company Application June 30, 1949, Serial No. 102,314In France July 19, 1948 Knitted material used for stockings and the likearticles of hosiery worn my people havi varicose veins areexecuted'usuall-y with thread that has a foundation of rubber andtextile fibre, and the rubber or gummy Substance contained thereinprovides for their elasticity but at the same time makes them unpleasantto wear and unhealthy on account of their imperviousness. What is more,from the very nature of such stockings, they are liable to deterioratewhen not worn. Furthermore, on account of their thickness and the way inwhich they are fashioned, such stockings have a somewhat roughappearance so that ordinary stockings have to be worn over them.

My invention removes these drawbacks and it has for its object astocking for varicose veins that is made up just like any other ordinarystocking of finely knitted mesh. This is a light weight, sturdy article,pleasant to wear, there is no restriction to the range of coloring thatmay be selected and customers may indulge in any particular fancy tokeep abreast with the fashions and chiefly it has the indispensablecharacteristic for stockings of this kind used in the treatment ofvaricose vein troubles i. e.

it is really an elastic stocking.

A stocking according to the present invention is illustrativelyexemplified in the accompanying drawing, which shows a side elevationalview of a full length stocking having a foot portion l0, leg section IIand open top I2.

It is a well known fact that there are threads with a foundation ofpolyamides that possess an extraordinarily high degree of durability,strength and more particularly of elasticity; the object of my inventionis the adaptation of these polyamide threads to the fashioning ofstockings for those afilicted with varicose veins.

For this purpose, the knitting of these stockings is carried out in aroom kept under invariable moisture conditions with superpolyamidethreads that have been subjected to twisting, that have been allowed tofreely shrink with the twist fixed and then untwisted, sized andsteamed; they are then milled and colored to the desired tint.

The superpolyamide thread is delivered in reels, after it has undergonea process of twisting, proper shrinking, fixing, untwisting that enablesit 'to assume later a fieecy appearance and feel, together with elasticand heat insulating properties that are several times greater than thoseof the original thread and, finally, resizing in view of the laterhandlings. The twist is fixed after the shrinking.

6 Claims. (01. 66-178) After being steamed, the material is then knittedin a room kept under constant moisture conditions, the knittingmay bedone on circular stocking frames or rectilinear knitting machines. Theknitted stocking is milled which, as a result of its previoustreatments, gives it a crepe effect, and consequently the desiredelastic quality. It may finally be dyed, the coloring operation mayfollow after the milling or be done at the same time. Milling is themechanical action of bathing the fabric in water containin a fattymaterial such as soap, to eliminate completely the sizing and so to freethe thread from all restriction so that each can freely take, withrespect to the others, the place which suits it.

This particular type of stocking is knitted just like the usual stockingand has a dainty enough appearance to avoid the necessity of having towear another stocking to cover it. The superpolyamide thread has anastonishing degree of elasticity and from this point of view it is justas good as stockings made of some rubbery material and textile fibre, itkeeps the veins compressed in proportion to their tendency to swell outwhen the wearer becomes tired. Finally, by reason of the elimination ofthe rubbery constituent, this stocking that shows no sign ofdeterioration when not worn is a very healthy article and enables theskin to breathe as well as with a stocking made of any artificialtextile thread.

Naturally, my invention is not in any way restricted, for the fashioningof this stocking, to the single treatment of the thread that has beenmore particularly shown; it takes in, on the other hand, all methods forobtaining a stocking in which use is made of superpolyamide thread forthe comfort of those suffering from varicose veins.

It is possible also to use simultaneously with the superpolyamide athread of a different nature.

What I claim is:

l. A method for producing a stocking for varicose veins consisting intwisting a superpolyamide thread, allowing same to shrink freely, fixingthe twist, untwisting the thread, sizing it, steaming the thread andknitting the stocking with said thread under constant hygrometricconditions.

2. A 'method for producing a stocking for varicose veins consisting intwisting a superpolyamide thread, allowing same to shrink freely, fixingthe twist, untwisting the thread, sizing it, steaming the thread andknitting the stocking with said thread and a thread of a differentnature under constant hygrometric conditions.
